I don’t think half of the dealers Persona’s are broke in. Paradigm will tell you 300 hours.
All I can say that with proper cabling and with tubes somewhere in the chain the Persona’s ( I have the 5f’s) are a great speaker. Absolutely kill my previous Magico S3.
Without a doubt out of the box with my previous cabling ( Audience AU 24 SX ) they sounded just as a lot of people describe, bright and uninvolving. With a more meaty cable loom of Cerious Technolgies graphene Matrix and a couple of months of break in this is a fantastic speaker. My friends have Martin Logan’s CLX, Wilson’s, Merlin’s, Revel Salons and the all love the Personas. Just have to have the right synergy. Probably some of the finest midrange you will hear in any speaker in its price range. I added Harmonix RF 909 spike bases and took them to another level. This really is a great speaker. Just needs a little time and effort to get there
